Use wildcards in sites blocking options (at least for notifications)

As usual, when one adds new capabilities, one will find trash who abuse it.
This is about the site pshntf.com who will generate random xxxxxx.pshntf.com domain names to repeatedly ask the right to push notifications on your computer.

I solved this problem by blocking the whole domain in my hosts file, but it would be much better if there was a possiblity to specify *.pshntf.com in the site wise notification config list.
